No. 655,741, filed July 25, 1967, and

Ser. No. 749,315, filed Aug. 1, 1968, both now abandoned.

Thisinvention relates to nail polish compositions containing as the coloring agent, a colored polymer in which the groups which impart color to the polymer are chemically bonded to the polymer molecule. i

It has long been known that nail polish or lacquer contains as essential ingredients a film former, a resin, a plasticizer, a solvent and a pigment. One of the most commercially acceptable film formers employed is nitrocellulose and specifically nitrocellulose designated as RS or SS,

the former containing about 11.2 to 12.8% nitrogen and being soluble in esterssuch as ethylacetate and itshomologues, ketones and glycol ethers, and the latter containing about 10.7 to 11.2% nitrogen and being soluble in mixtures of alcohol and toluene, with the former being preferred.

Known resins usefully employed in prior art nail polishes, enamels or lacquers include synthetic drying and non-drying alkyd resins, polyvinylacetate, various polyester resins and arylsulfonamide-formaldehyde resins.

:ate, butyl phthalyl, butyl glycolate, dicoctyl phthalate, butyl stearate, triphenyl phosphate, triethyl citrate, camphor, castor oil, dibntoxy ethyl phthalate, dibutyl tartrate and diamyl phthalate.

In known nail polishes or lacquers which are nitrocellulose-based, the solvents employed have been generally classified in three interrelated categories, i.e., as active solvents, couplers or latent solvents and as diluents. Active solvents include esters, ketones and glycol ethers and are true solvents for nitrocellulose. Couplers are generally a1- cohols including ethyl alcohol, isopropylalcohol, n-butylalcohol and amyl alcohol, while diluents are generally aromatlc and aliphatic hydrocarbons such as hexane, toluene, xylene and light petroleum naphthas.

However, one of the more limiting criteria for producing an acceptable nail polish or lacquer in the past has been the choice of the coloring agent to be employed in the desired formulation. Thus, as pointed out in Cosmetics, Science and Technology, Ed. Edward Sagarin, Interscience Publishers, 1966 at p. 683, the choice has been limited essentially to coloring agents which are insoluble or substantially insoluble in lacquer solvents so as to avoid staining and discoloration of the nails and which will not react with the lacquer vehicle. The author, continuing on p. 684 of this reference, states that soluble dyes are only sparingly used because of their staining characteristics on the users skin or nails and generally are employed only to tint lacquer removers. It has also, however, been known to use solvent-soluble dyes in very special cases in which a very slightly colored polish is desired, i.e. one which imparts a very pale tint to the nail. However, it has been found that if an attempt is made to obtain polishes with lasting shades using coloring materials which are soluble in the polish, the coloring material also dissolves in the keratinic substance composing the nail, especially after repeated applications, so that after the polish has been removed by a solvent, the nail remains discolored or stained.

Insoluble coloring agents or materials recommended in the above reference include the lithols (D-& C Reds Nos.

10, ll, 12 and 13), lithol rubines (D 8: C Red N0. 7)

and TOB-BON Maroon (D & C Red No. 34). A few lake colors have also been suggested such as D8: CYellow No. 5 Lake, D &C Red No. 2 Lake and Ext D& CRed No. 2 Lake. In addition to these organic coloring agents, such inorganic materials as cosmetic grade or purified titanium dioxide, yellow and red iron oxides, iron blue, iron black, ultramarine blue and chrome oxide greenshave also been suggested for use in nail polish or lacquer formulations as the coloring agent. But one important criteria in the choice of the coloring agent is its non-staining efiect on the skin or nail and the common characteristic of those coloring agents heretofore employed has been its insolubility in the nail polish composition. I 1.

The use of such insoluble coloring agents has serious drawbacks because the resulting nail polish or enamel lacks I adesirable degree of luminosity which is a sought-after With regard to the latter, equimolecular proportions of characteristic in transparent polishes. This drawback is further accentuated when pearlescent and colored polishes are desired since the opacity imparted to the polish by the inorganic or non-soluble coloring agents, masks to a large extent the desired pearlescent efiect. V

The applicant has, however, by-the present invention overcome the disadvantages of prior art nail polishes and has provided a nail polish or lacquer containing a soluble coloring agent, which polish is transparent and contains vivid and lasting colors but which does not have any substantial deleterious staining eflect on the nail or skin. Further, the nail polishes of the present invention can contain materials which produce a pearlescent effect which remains essentially unmasked notwithstanding the'deep 3 coloration that can be imparted thereto, since the polish remains essentially transparent. Additionally, the nail polish of this invention can include white pigments to produce a creamy appearance having a brilliance and freshness of tint which has not heretofore been achieved.

In accordance with the present invention there 1s provided a nail polish composition comprising about 12- 15 weight percent film former, about 6-13 weight percent resin, about -8 percent plasticizer, about 1-15 percent coupler, about 12 32 Weight percent diluent, about 0.5-6 weight percent colored polymer as the coloring agent, the remainder being, essentially, solvent.

Preferably, the film former is nitrocellulose and as stated herein before lacquer grade nitrocellulose designated as RS and SS can be employed although RS nitrocellulose is preferred. Representative viscosity ranges of the preferred RS nitrocellulose include RS sec., RS /2 sec. and RS /1 sec.

Preferably the resin utilized in the nail polish composition of this invention is aryl sulfonamide formaldehyde resin sold under the trade name Santolite MHP. This resin has a softening point of approximately 62 C., is brittle at ordinary temperatures, is nearly colorless and is insoluble in-drying oils but soluble in many organic solvents. Additionally it is compatible with nitrocellulose and most plasticizers.

As the plasticizer, there is employed, preferably, camphor or dibutylphthalate.

Propanol, isopropanol, butanol and ethanol are preferably used as couplers, while xylene and toluene are employed as diluents. Representative preferred active sol vents utilized include acetone, ethyl acetate, butyl acetate and methylacetate.

When it is desired to impart a pearlescent or iridescent effect to the nail polish or lacquer there is employed a nacreous substance such as that sold under the trade name Mearlmaid, a natural pearlescence or, similarly, essence of the Orient. This nacreous or pearlescent material can be employed in amounts of about 6-10 weigh percent of said composition.

Inorganic pigments, such as titanium dioxide in amounts of about 1-3 weight percent can also be included in the novel nail polish composition of this invention.

As stated before, an important and critical concept of the present invention resides in the incorporation in the nail polish composition, as a coloring agent, of a colored polymeric material which is soluble therein to provide a composition which exhibits essentially no nail or skin staining effects.

Representative colored polymers which can be used in accordance with the present invention are:

The colored polymers comprising amide functions whose azotized portion consists of color-imparting groups consisting of aromatic diamines and, particularly, such polymers derived from acrylic amide.

These colored polymers, as well as processes for preiparing them, are described in French Pat. No. 1,309,399

of Oct. 5, 1961, granted to applicants assignee.

The copolymers made from monomers which can be used for obtaining resins compatible with the nail polishes, together with at least one monomer comprising a reactive chlorine to which at least one color-imparting group :is chemically attached by quaternization.

-The monomers containing a reactive chlorine can include, for example, vinyl chloroacetate or N-allylchloracetamide.

The other monomers which can be used to obtain resins compatible with nail polishes include, for example, vinyl esters such as vinyl acetate, vinyl lactams such as vinyl pyrrolidone, alkyl acrylates and methacrylates, substituted or unsubstituted acrylamides and methacrylamides, or unsaturated carboxylic acids such as crotonic acid, acrylic acid, methacrylic acid or itaconic acid.

Representative coloring agents which can be used for these polymers are those having a tertiary amine function.

These coloring agents can be chemically bonded, by quaternization, to polymers having oneor more reactive chlorine atoms. Among these coloring agents are the azo dyes, the anthraquinone dyes, the azine dyes, as well as dyes derived from nitrophenylenediamines and quinolines.

Such dyes can be quaternized on the groups of these colorless copolymers containing a reactive chlorine such as'vinyl chloroacetate or N-allyl-chloracetamide.

The preparation of such colored polymers can be made by introducing the monomers into a flask provided with an agitator, a reflux condenser, a thermometer and a tube for admitting nitrogen. A lower alkanol, such asethanol and a catalyst such as diazoisobutyronitrile are added to the reactants. The mixture is heated to reflux for a sulficiently long period, i.e. up to and including, for instance, 20 hours to produce the colorless polymer which, after cooling, is admixed with ether to precipitate the colorless copolymer.

The resulting colorless copolymer and the dye can then be introduced into a reaction vessel provided with agitating means and a reflux condenser. To the vessel there is also introduced a solvent such as dioxane. The reactants are then heated to reflux. The resulting colored polymer is then precipitated and separated from the reaction mass.

There can also be used colored polymers made from monomers which are used to obtain resins compatible with nail polishes, together with at least one monomer having a reactive epoxy function to which an extra-nuclear amine dye is chemically bonded by condensation of its primary or secondary amine function.

Monomers comprising an epoxy function can be, for example, glycidyl methacrylate, glycidyl acrylate or allylglycidyl ether.

The other monomers which can be used to obtain resins compatible with nail polishes can be, for example, vinyl esters such as vinyl acetate, vinyl lactams such as vinylpyrrolidone, alkyl acrylates or methacrylates such as substituted or unsubstituted acrylamides or methacrylamides.

Representative extra-nuclear amino dyes which can be used to obtain these colored polymers are those corresponding to the following formula:

in which: p is 26, R is selected from the group consisting of hydrogen, CH and C H andthe Col. represents a cyclic or polycyclic dye selected from the group consisting of benzene and anthraquinone dye. A I

Among the dyes responding to the above definition, those having one or two supplementary amine function's attached directly to their ring are particularly useful.

These colored polymers can be prepared according to various known proceses. However, it seems preferable to carry out the polymerization in a solvent such as dioxane, dimethylformamide or a ketone, in thepresence of a catalyst such as benzoyl peroxide or azodiisobutyronitrile and heating to reflux after which the copolymer can be precipitated by the addition of ether, for instance, to the cooled reaction mass. The condensation with the epoxy group and thebondmg of the dye to the resin can be carried out by heating the dye and the colorless copolymer in a solvent such as dimethylformamide, dioxane or a ketone and heating to reflux. The progress of the condensation reaction can easily be followed by measuring the progressive disappearance of the epoxy group. I Colored polymers also usefully employed in the present invention are those formed by the simultaneous condensatron of at least one alcohol and either at least one hydroxylated colorant, at least one amino colorant or a mixture of these two types of colorants on a polymer obtained by copolymerizing equimolecular quantities of maleic anhydride and an unsaturated monomer. t

7-; The groups in these colored polymers The alcohol and the colorant or colorants can be condensed for example on a copolymer having recurring units of the formula:

wherein: R and R" each independently are selected from the group consisting of hydrogen, a lower alkyl having 14 carbon atoms, phenyl and lower alkoxy having 1-4 carbon atoms, R'" is selected from the group consisting of hydrogen, OCCH CEN and COOCH "Representative of such copolymers are maleic anhydride/-vinylalkyl ethers, maleic anhydride/ ethylene, maleic anhydride/vinyl acetate, maleic anhydride/alkyl acrylate or alkyl methacrylate, and maleic anhydride/acrylonitrile copolymers. This list, however, is not exhaustive.

Colored polymers of this type can advantageously have the following formula: I I a wherein:

R, R and R'" have the meanings formula I,

R is a lower alkyl having 1-4 carbon atoms such as R represents the remainder of a dye comprising a hydroxyl function,

R represents the remainder of a dye comprising a primary or, secondary nuclear'or extra-nuclear amino function, p, :q, and r represent whole numbers and either q or r may equal 0 but both cannot equal 0 simultaneously.

Among the polymers corresponding to the above formula, polyacrylic chloride is particularly useful and can be easily obtained by polymerizing acrylic chloride in presence of azo-bis-isobutyronitrile, which acts as a catalyst.

--CH and C H and Col. represents a cyclic or polycyclic dye selected from the group consisting of azo, benzene and anthraquinone dye.

Among the dyes responding to the above definition those having one or two supplementary amine functions attached directly to their ring are particularly useful.

The preparation of these colored polymers can easily be carried out by condensing the dye or dyes on the polymers in the presence of an. appropriate solvent which is inert with respect to the dyes.

The colored polymers can also be prepared by condensing the dye on monomers having reactive groups which can form an amide bond with the extra-nuclear amino dyes and then proceeding to a polymerization or copolymerization. I

For instance, a copolymer in an alcoholic solution and a dye having an extra-nuclear amino radical together with a lower alka'nol, such as ethanol, are placed in a flask equipped with a thermometer and a reflux condenser. The reaction mass is heated to reflux to produce said colored polymer. The present invention also contemplates the use of colored polymers whose macromolecular chain consists of a homopolymer to which at least one amino colorant is attached by a chemical bond of the amide type.

The amino dye used to color the homopolymer can consist of an extra-nuclear amino dye in which the nitrogen of the extra-nuclear amino function is used to form tihe amide bond linking the dye to the homopolymer.

The extra-nuclear amino dyes having the following formula are particularly useful:

Col.-(CH ),N

wherein:

p is 2-6,

R is selected from the group consisting of hydrogen, OH;, and -C H and Col. represents a cyclic or poly-cyclic dye selected from the group consisting of benzene and anthraquinone dye.

Among the dyes having the above formula are, for example, those having at least one other amine function substituted directly on their ring in addition to the amine function used for attachment to the polymer.

Among the homopolymers which can be used are the organic acid anhydrides having an ethylene bond such as -poly(maleic anhydride), poly(itaconic anhydride), poly (acrylic' anhydride), poly(methacrylic anhydride) and poly(mixed acrylic/methacrylic anhydride).

These colored polymers can be prepared by introducing the poly(organic acid anhydride), a suitable solvent such .as anhydrous dioxane, the dye and a lower alkanol such as n-butanol in a flask equipped with agitating means, a thermometer and a reflux condenser. The mixture. is heated to reflux and esterification can be completed, if desired, by further addition of lower alkanol and further heating to reflux. The resutling colored polymer is then precipitated by addition to the reaction mass of, for instance, petroleum ether and separated therefrom.

Still other colored polymers usefully employed in the present invention are polymeric materials obtained by polymerization of an unsaturated organic .anhydride selected from the-group consisting of itaconic anhydride, .citraconic anhydride and acrylic anhydride with an ethylenically unsaturated monomer selected from the group consisting of maleic anhydride, vinyl, acetate, isobutyl wherein p is 2-6,
